UX Writing for Conversion#

When to Use#

Use this skill when writing or reviewing interface copy — labels, instructions, confirmations, error messages — to improve usability and conversion.

Core Rules#

1. Write for Action, Not Description#

Interface copy should prompt action, not describe features. "Analyze my landing page" on a button converts better than "Analysis Tool." "See where users drop off" beats "View Analytics." Every piece of copy should answer: what will the user do or get?

2. Use Plain Language at All Literacy Levels#

Your product's interface will be used by people with varying technical literacy. Write at a Grade 8 reading level: short sentences, common words, no jargon. If a 14-year-old couldn't understand your interface copy, rewrite it.

3. Front-Load Important Information#

Users scan interfaces rather than reading them linearly. Put the most important word or concept at the beginning of labels, headings, and instructions. "Free plan: 5 tests per month" is more scannable than "With the free plan, you can run up to 5 tests per month."

4. Be Consistent With Terminology#

Using "workspace," "project," and "account" interchangeably to mean the same thing creates confusion. Establish a glossary of terms for your product and use them consistently across every surface: UI, emails, help docs, and marketing.

5. Write Error Messages That Solve Problems#

Error messages are the most important UX copy in your product and the most neglected. A good error message explains what went wrong, why it happened, and exactly what the user should do next. Bad error messages blame users or provide no actionable path forward.

Common Mistakes to Avoid#

• Using technical or database language in user-facing copy
• Writing placeholder text that doubles as a field label — it disappears on focus
• Inconsistent capitalization and punctuation — creates a perception of low quality
